Answer:
88
Step-by-step explanation:
You're trying to find the circumference of a circle. The general formula is: pi•D. D is the Diameter. 22/7 is the fraction version of Pi, so just do 3.14x28 and you will get your answer. 88
Answer:
B=16over37
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
15(15b−7)=3b−9
(15)(15b)+(15)(−7)=3b+−9(Distribute)
225b+−105=3b+−9
225b−105=3b−9
Step 2: Subtract 3b from both sides.
225b−105−3b=3b−9−3b
222b−105=−9
Step 3: Add 105 to both sides.
222b−105+105=−9+105
222b=96
Step 4: Divide both sides by 222.
222b
222
=
96
222
Then simplify
FOIL (distriute)
tells how to multiply which ones
First terms
Inner terms
Outer terms
Last terms
(2n+2)(6n+1)
First (2n times 6n=12n^2)
Inner (2 times 6n=12n)
Outer (2n times 1=2n)
Last (2 times 1=2)
add them
12n^2+12n+2n+2
12n^2+14n+2
The correct answer is x= 94
